EGW 1911 Mainspring Housing – 25 LPI – Blued Steel
Upgrade your 1911 with the EGW 25 LPI Blued Steel Mainspring Housing, a premium component designed to enhance grip, balance, and overall control. By replacing your factory housing, you immediately improve the feel of your pistol, making every shot more consistent and every reload smoother. Additionally, this flat-profile housing preserves the classic 1911 look while offering modern durability and precision.
Precision 25 LPI Checkering for Maximum Control
EGW carefully machines 25 lines per inch (LPI) checkering on this mainspring housing to provide optimal grip and control. As a result, your hand stays securely planted during recoil, rapid-fire sequences, or extended practice sessions. Furthermore, the checkering feels comfortable and natural, giving shooters confidence in every shot. This thoughtful design ensures that your pistol tracks consistently, improving both accuracy and handling under demanding conditions.
Solid Bar-Stock Steel Construction for Long-Term Reliability
Crafted from solid bar-stock steel, this mainspring housing offers superior strength and longevity compared to plastic or cast alternatives. Consequently, it resists wear, deformation, and corrosion, ensuring that your upgrade lasts through years of rigorous use. Moreover, EGW applies a durable blued finish, which not only protects the steel from corrosion but also enhances the visual appeal of your 1911. Therefore, your pistol maintains a professional, classic look while benefiting from modern materials and craftsmanship.
Classic Flat 1911 Design for Easy Installation
The flat-profile design of this housing maintains the clean, traditional 1911 style. In addition, the drop-in fit allows for quick and effortless installation in virtually any full-size 1911 handgun, including Government and Commander frames, as well as full-size Para-Ordnance models such as the P-14 and P-16. Consequently, you can upgrade your pistol without the need for additional fitting or gunsmithing modifications.
Ideal Replacement for Worn or Plastic Housings
Many factory 1911s come equipped with lightweight polymer housings that can feel imbalanced or wear quickly. By upgrading to this solid steel mainspring housing, you not only add rearward weight for improved balance, but you also enhance overall handling and control. Furthermore, this housing serves as a reliable replacement for worn, damaged, or low-quality plastic components, ensuring consistent performance for years to come.
Installation Notes
Pins and springs are not included with this mainspring housing. However, you can reuse the components from your original housing or purchase a replacement mainspring kit separately. Installation remains straightforward for anyone familiar with standard 1911 maintenance procedures. Moreover, using existing pins and springs allows for a seamless transition from your factory setup to this upgraded housing.
